264 MEMOIRS OF THE XEW YORK BOTANICAL GARDEN. 



* Viola monticola. 



Stems numerous, from a woody rootstock, very short, less than 5 

 cm. hi(jh, densely pubescent with short hairs ; stipules 0.5-1 cm. long, 

 lanceolate, entire or sometimes bristle-toothed ; leaves on very short 

 petioles, denseh' puberulent ; blade broadly ovate, truncate or cordate 

 at the base, about 2 cm. long, obtuse, finely crenate : peduncles 

 short, about 2 cm. long; sepals broadly lanceolate; petals blue 

 with 3'ello wish- white base, narrow, obovate, 5-8 mm. long, the lat- 

 eral ones bearded; spur about 5 mm. long, curved upwards; pod 

 ovoid, 5-8 mm. long ; seeds like those of the preceding species. 



Resembles in many respects the foregoing species, but is a much 

 smaller plant, with very short stems, small leaves and broad se- 

 pals. Resembles much more V. arenaria, from wh'ch it differs in the 

 subentire stipules, the color and the form of the spur. On dry hills 

 in southern Montana, at an altitude of 1800-2500 m.

Stems several from a rather slender perennial root, 5-8 dm, high, 

 sparingly and minutely puberulent, more or less striate ; stipules 

 5-8 mm. long, toothed with slender linear-subulate teeth: leaves 

 round-cordate, obtuse, slightly crenate, finely puberulent or in

 margined; peduncles 4-5 dm. long, with one or two small linear 

 bracts a little above the middle ; sepals linear-lanceolate, about 6 mm. 

 long ; petals purple or the lower portion yellowish white, more or 

 less distinctly purple-veined, over i cm. long; spur short, about 5 

 mm. long, strongl}- saccate at the end, where it is 3 mm. in diameter, 

 and strongly tubercular-toothed on the upper side.

 differs in the form of the spur.
